The ARB RD101 Air Locker is the industry standard for selectable traction, allowing you to transition from an open differential for street driving to a 100% locked axle for technical off-roading with the flick of a switch. This pneumatically operated system prevents internal differential gears from rotating, ensuring both axle shafts turn at the same speed to maintain maximum traction in mud, rocks, or snow. The RD101 features a high-strength two-piece design with a patented timed locking mechanism for ultra-fast engagement and superior durability.
